Adams & Arapahoe County Birding

September 24, 2011

Richard Stevens:

Bryan Ehlmann and I returned to Rocky Mountain Arsenal when they opened at 6:00 am. Again, no Long-eared Owls were found flying around the Governor's row.

We hiked the south side of Lake Ladora and circled back to the northeast corner. A Virginia Rail was heard calling from the south side cattails. A Townsend's Warbler fluttered about the tall cottonwoods at the southwest corner of the lake.

A loose flock of birds moved from east to west at the edge of the trees at the northeast corner. Yesterday's Cassin's Vireo was with a Red-eyed Vireo, 9-11 Yellow-rumped Warblers (mostly Myrtle), 4 Black-capped Chickadees, and an Orange-crowned Warbler.

Yesterday's Tennessee Warbler was not found.

Another Townsend's Warbler was at the Rod & Gun Club Trailhead (perhaps the same bird seen a little farther east yesterday)? The only bird found around the bird blind was a Rock Wren.

After dropping Bryan off at home, I heard about the great birds being seen at Barr Lake (Adams) and headed over that way. I spent three hours walking around the banding area.

Few birds were encountered. Three brief unsatisfying glimpses of the male Black-throated Blue Warbler were seen at the extreme end of the point of land & trees that jut into the lake.

Several Wilson's Warblers were found, all three more or less by themselves. No flocks of birds moved about (it was 2:00 pm, not the best time of day to search for birds).

Missed birds included the Cassin's Kingbird, Philadelphia Vireo and the Tennessee Warbler.

I picked up Rebecca Kosten and drove into Denver for dinner. We passed Aurora Sports Park (Arapahoe) and could not resist stopping for a quick look around. A Sage Thrasher was on the fence at the extreme southeast corner of the park.

I made a quick hike into the woods at the northeast corner of the riparian woods. There is a grove of short trees and bushes under the tall cottonwoods, which on many occasions have attracted some uncommon birds.

The area was quite birdy again today. I counted 11 Yellow-rumped Warblers, 2 Orange-crowned Warblers, 2 Wilson's Warblers, 2 Wilson's Warblers and 6 Black-capped Chickadees. The prize with this flock was a Palm Warbler pumping his tail!

We stopped to watch the sunset at the west end of East 11th Avenue (off Picadilly Road). Hundreds of White-cheeked Geese flew overhead. Another Sage Thrasher was on a fence post.

This small subdivision of homes has a Eurasian Collared-Dove problem. We counted 80+ doves in the thick windbreaks around the houses.
